Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641612, here are decompositions:

41 + 8641571 = 8641612
71 + 8641541 = 8641612
179 + 8641433 = 8641612
191 + 8641421 = 8641612
251 + 8641361 = 8641612
263 + 8641349 = 8641612
281 + 8641331 = 8641612
293 + 8641319 = 8641612

Showing the first eight; more decompositions exist.
